Collins joined Town on loan at the start of September after being left out of Stoke's 25-man Premier League squad.
He has settled quickly with the Championship club and has struck up a formidable partnership with Sonko at the heart of Paul Jewell's back four.
His loan agreement is only set to run until December, but it is hoped that a deal can be put in place to keep the 31-year-old at Portman Road past that point.
"I really hope Danny stays. He is a wonderful player and a wonderful team-mate," Sonko, who has also played alongside Collins at Stoke, told the Green'Un.
"We just understand each other. He has got his way of playing and I have mine, but it seems to be working.
"We talk a lot on the pitch. He is not scared of telling me what he thinks and he can be a bit aggressive. He loves to get stuck in and he doesn't like losing.
"I am a bit more peaceful and sometimes I need roughing up a bit."
